# GitHub Copilot

> Use Fireworks AI models in GitHub Copilot Chat via a custom endpoint

Use [Fireworks AI](https://fireworks.ai) models in **GitHub Copilot Chat** by adding a **Custom Endpoint** in VS Code (or other hosts that support Copilot custom models).

<Info>
  Fireworks offers **200+ models**—copy the model `id` and token limits from the [Model Library](https://app.fireworks.ai/models). Use endpoint URL `https://api.fireworks.ai/inference/v1`.
</Info>

## Prerequisites

* A Fireworks [API key](https://app.fireworks.ai/settings/users/api-keys)
* GitHub Copilot with access to **Other Models** and **Custom Endpoint** (availability depends on your Copilot plan)

## Setup

<Steps>
  <Step title="Open model settings">
    In Copilot Chat, click the active model name at the bottom (often **Auto**). In the menu, click the gear icon next to **Other Models**.
